Check chrome on the rod for wear, Chrome if needed.

Check Barrel for wear, Hone or replace if needed.

Check Rod Bushing for wear, Hone or Replace if needed.

ASSEMBLY

Clean all parts before the unit is assembled.

Assemble unit using Fyrquel compatible Seals and Piston rings.

Torque all bolts to the Manufacturers Specifications.

MANIFOLD

Disassemble the Manifold and flush all ports.

Rebuild the Check Valves.

Rebuild the Skinner Valve and Test separately.

FINAL TEST

Install all the valves and filter to the manifold, then assemble the manifold to the Actuator for Final Test.

Test and Cycle at 2000 PSI, Unit is checked for internal and external leakage.

Fyrquel EHC fluid used for Testing drained after test.

Unit is Epoxy painted to protect from corrosion.

A Service Report is sent with the repaired unit documenting the processes required for the repair.

PRICE WILL BE QUOTED BEFORE THE REPAIR IS STARTED FOR CUSTOMER APPROVAL.
